RUBBlNG-MOTION FORCARDING-ENGINES' SPECIFICATION forming part of Letters Patent No. 467,093, dated January 12, 1892.

Application filed July 2'7, 1891. Serial No. 400,823. (No model.)

To aZZ whom it may concern.-

Be it known that I, WEBSTER GILL, a citizen of the United States, and a resident of Camden, Camden county, New Jersey, have invented certain Improvements in Rubbing- Motions for (larding-Engines, of which the following is a specification.

The object of my invention is to so construct the rn bbing mechanism of carding-machines as to dispense entirely with the slideguides usually employed, thus reducing the friction between the parts and preventing the splashing of oil.

In the accompanying drawings, Figure 1 is a transverse sectional view of suflicient of a rubbing-motion to illustrate myinvention. Fig. 2 is a side view looking in the direction of the arrow, Fig. 1; and Fig. 3 is a perspective view of one of the operating-levers.

' It will be understood that my invention is adapted not only to apron-rubbers, but also to. roll-rubbers, and it will also be understood that the rollers or aprons are given a laterally-reciprocating motion and constant forward or rotary motion, as usual.

Heretofore the journals of the rub-rolls or apron-rollers were either mounted in crossheads, which were adapted to guides on the f rame-work of the machine or were adapted to hollow shafts, the friction between the parts, especially when subjected to the tension of rubbing-aprons, being very great and the parts requiring special attention. I dispense with these ordinary frictional surfaces in the manner which I will now proceed to describe.

A is the frame-work of the machine, of any suitable form.

B B are the upper rubbing-aprons, and O C the lower rubbing-aprons, the upper aprons being adapted to drums b b and the lower aprons to drums c c, as shown in Fig.2. The shafts D D of the upper sets of drums Z) Z) are adapted at each end to bearings in crossbars F F, and the shafts E E of the lower sets of drums c c are adapted at each end to bearings in like cross-bars G G.

On one sideof the machine are two sets of levers H II, carried, respectively, by f ulcru mshafts H H, adapted to suitable bearings h h on the frame of the machine, and on the opposite side of the machine are similar setsof levers I I, carried by fulcrum -sha fts I 1 adapted to bearings i. The upper arms of the levers H and I have boxes h for the reception of the trunnions of the bars F, the lower arms of these levers carrying the bars G, and in like manner the upper arms of the lovers II and I carry the bars F, and the lower arms of said levers carry the bars G. I prefer to cast the levers II I H l with the shafts; but I may find it advisable to make them separately and secure them in any mannor to the shafts, and the number of levers on each shaft can be increased as the construction of the machine demands.

Projecting from the shaft II is a slotted segmental arm H and adapted to the slot in said arm is an adjustable blockj, coupled to the eccentric-rod J of an eccentric J on' the driving-shaft M, and the shaft 11 has a similar slotted segmental arm H to which is adapted an adjustable block 7.3, the strap K of which is adapted to an eccentric K on the shaft M. By this means the desired lateral reciprocation of each pair of apronsB B and C O in opposite directions is effected.

By moving the blocksj and 7c on the arms H toward or from the fulcrum-shafts the extent of lateral reciprocation of the aprons can be diminished or increased, as desired.

The fulcrum-shafts H II and I I are the same distance apart vertically as the axes of the aprons B B and O C, so that said aprons always bear the same vertical relation to each other.

One set of rollers b b is geared together by spur-wheels n n, the wheel n being geared to the driving-pinion n on adriven shaft N, the faces of the wheels at n being so wide that the shafts will be in gear at all times during their lateral movement. The rolls 0 c of one set are geared in a similar manner to each other and to a driving-shaft I.

It will be seen that I dispense with the slide-guides usually employed, and I mount the eccentrics for giving the necessary rubbing motion at the base of the machine, and can make them much smaller than those usually employed, as I obtain the desired throw by the use of levers, and I can regulate the transverse movement of the aprons or rub-rolls by simply adjusting the blocks on the arms H thus increasing or diminishing the stroke of the rubbers without neces;

sitating any change or adjustment of the eccentrics themselves, as usual.

By mounting the eccentrics at the base of the machine away from the rub rolls or aprons,I overcome an objection to eccentrics mounted on a vertical shaft opposite each set of rubbers-namely, the splashing of oil from the eccentrics onto the rubbers or onto the fibers which are being rubbed.

It has been customary to provide an eccen trie for each line of rubbers. Thus on a twohigh rubber four eccentrics were needed, two for each set; but I so arrange the parts that only two eccentrics are needed.

I have illustrated my invention as applied to a machine having two lines of rubbingaprons, necessitating the use of two-armed levers; but it will be understood that when but a single set or line of rubbing-aprons is mounted on the levers one set of carryingarms may be dispensed with, and when rubrolls are employed they may be carried by bars F F and G G in the same manner as the rollers of the aprons. Cranks or cams may also, as will be evident, be used in place of eccentrics for actuating the levers, and hence such substitutes are considered to be the equivalents of the eccentrics.

same, and means for vibrating the levers, the upper rubber of each set being carried by one set of levers and the lower rubberof each set by another set of levers, substantially as specified.

3. The combination of upper and lower sets of rubbers with opposite levers and means for vibrating the same, one set of levers can rying the upper rubbers of each set and the other set of levers carrying the lower rubbers of each set, the fulcrums ot' the two sets of levers being separated vertically to the same extent as the axes of the upper and lower rubbers of each set, substantially as specified.

4. The combination of the rubbers of a carding-machine, bars carrying the same, opposite levers to which said bars are hung, and means for vibrating said levers, substantially as specified.

5. The combination of the rubbers of a carding-machine, opposite levers carrying said rubbers, arms connected to said levers, and operating-eccentrics having rods con nected to said arms, substantially as specified.

6. The combination of the rubbers of a carding-machine, opposite levers carrying said rubbers, slotted arms connected to said levers, and operating-eccentrics having rods adjust-ably connected to said slotted arms, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
